Sean Busbey resolved HBASE-8386.
--------------------------------
Resolution: Fixed
Release Note: The MapReduce helper function
`TableMapReduce.addDependencyJars(Configuration, class<?> ...)` has been
deprecated since it is easy to use incorrectly. Most users should rely on
addDependencyJars(Job) instead.
> deprecate TableMapReduce.addDependencyJars(Configuration, class<?> ...)

> We expose two public static methods names {{addDependencyJars}}. One of them,
> {{void addDependencyJars(Job}}, is very helpful -- goes out of its way to
> detect job dependencies as well as shipping all the necessary HBase
> dependencies. The other is shfty and nefarious, {{void
> addDependencyJars(Configuration, Class<?>...)}} -- it only adds exactly what
> the user requests, forcing them to resolve dependencies themselves and giving
> a false sense of security. We should deprecate the latter throw a big giant
> warning when people use that one. The handy functionality of providing help
> when our heuristics fail can be added via a new method signature, something
> like {{void addDependencyJars(Job, Class<?> ...}}. This method would do
> everything {{void addDependencyJars(Job}} does, plus let the user specify
> arbitrary additional classes. That way HBase still can help the user, but
> also gives them super-powers to compensate for when our heuristics fail.
> For reference, this appears to be the reason why HBase + Pig doesn't really
> work out of the box. See
> [HBaseStorage.java|https://github.com/apache/pig/blob/trunk/src/org/apache/pig/backend/hadoop/hbase/HBaseStorage.java#L730]
